假设访问页面地址为： http://www.abc.com/test.jsp

www.abc.com 域名解析到ip: 192.168.0.1 则curl访问方式为如下：

curl -H "Host:www.abc.com"  "http://192.168.0.1/test.jsp"
  • 实际测试http协议没问题, https协议就像下面一样了
[root@localhost ~]# curl -H "Host:wx.jiayuanshu.net"  "https://139.224.18.242"
curl: (60) Issuer certificate is invalid.
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
  • 解决办法, https时使用 --resolve 方法去实现
curl -H "Host:wx.jiayuanshu.net"  "http://139.224.18.242"
curl --resolve 139.224.18.242:443 "https://wx.jiayuanshu.net"

  • 查看php版本
[root@xgblog ~]# php73 -v
PHP 7.3.20 (cli) (built: Jul  7 2020 07:53:49) ( NTS )

  • 加个软链, 方便自己
[root@xgblog bin]# which php73
/usr/bin/php73
打开到 /usr/bin/ 目录, ls -la 可以判断实际指向到/opt/remi/php73/root/usr/bin/php
# 创建软链
ln -s /opt/remi/php73/root/usr/bin/php /usr/bin/php
[root@xgblog bin]# php -v

  • 重启php服务
systemctl restart php73-php-fpm
  • 确定9000端口被打开
[root@localhost ~]# netstat -nl

  • 编辑nginx配置文件, 参考下面的编辑方式
vim /etc/nginx/nginx.conf
>
server {
    listen       80;
    server_name  abc.de.com;
    root   /var/www/html;
    index  index.php index.html index.htm;
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    access_log /dev/null;
    error_log  /dev/null;
    

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

# 下面的内容拷贝到对应的位置
    location ~ \.php {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;

        fastcgi_split_path_info  ^(.+\.php)(/.*)$;
        fastcgi_param  PATH_INFO $fastcgi_path_info;
        include        fastcgi.conf;
    }
}
  • 设置php服务开机自启动
systemctl enable php73-php-fpm

# 更多php相关操作
systemctl restart php73-php-fpm #重启
systemctl start php73-php-fpm #启动

  • 使用proc进入程序使用的数据目录
/proc/3945/cwd
  • 通过配置的env文件得出这个是一个消息推送的微服务
然后重启这个容器, 就好了, cpu也不再飙高了

  • demo1, 支持待空格的文件拷贝, 不支持目录拷贝
#!/bin/bash
mkdir old_version

copy_from=`pwd`;
copy_to=`pwd`/old_version/;
for file in $copy_from/*;
    do
        cp -rfavx "$file" "$copy_to";
    done
# cp -rf "/home/bash/testgit/git1/111 - 副本 (5).txt" "/home/bash/testgit/git1/old_version/"
# exit;
